#Measles update: The confirmed case count this year has risen to 1792 cases as of 4/24/26.
To put that in context: In just under 4 months, 2026 has racked up 78% as many measles cases as were confirmed in the entirety of 2025. Only 10 were contracted abroad. https://t.co/ISiehghO0i

A measles outbreak in South Carolina (993 cases, 20 hospitalizations, 5 months) cost an estimated $35.5M- about 6.7% of the state public health budget!

Vaccinating the same group? Just $66K–$134K. Every $1 spent on vaccines could’ve saved $536.

Prevention isn’t just smarter- it’s dramatically cheaper. Put another way, more measles outbreaks means higher taxes - for everyone. 🤷🏽‍♂️

2 doses of the measles vaccine is 97% effective at preventing infection. If your kids are not yet vaccinated talk to your pediatrician. https://t.co/Cs8Y44G4Al

A recent study confirms that administering the #hepatitisB #vaccine at birth is safe and significantly reduces infections, countering the CDC's new position on delaying the vaccine. Hepatitis B poses serious health risks, including cancer. https://t.co/Hr1WpovCoR
